DOOR HOLDING DEVICE Filed Dec. 18, 1928 iii xiiazaaflw Patented Jan. 26,1932 UNITED STATES PATENT OFFICE LEON SAIVES, OF PARIS, FRANCE,ASSIGNOIB- TO LOUIS RENAULT, OF IBILLANCOURT,

' SEINE, FRANCE DOOR HOLDING DEVICE Application filed December 18, 1928,Serial No. 826,790, and in France February 11, 1928.

The present invention relates to an arrangemcnt for absorbing shocks andvibrations, which is chiefly applicable for use as a door-holder formotor vehicles.

The said arrangement consists essentially of two rubber bands providedwith teeth or corrugations, which are placed in the opposite position onthe door leaf and frame. The said bands are mutually engaged by theircorrugations, and will thus obviate all disagreeable noise due to theonly parts in contact of the door leaf and the vehicle body. Also, theelastic action of the two rubber bands in contact will prevent anyslight motion of the door leaf with reference to the vehicle body.

in the accompanying drawings, Figure 1 is a sectional view of the doorleaf and frame, provided with the device according to the invention, andF i ure 2, is a sectional view on a larger scale 0 a rubber facing, onthe line A-B of Figure 1.

With reference to the drawings, it will be observed that as concernsthe-use of the device upon motor vehicles, the door frame or vehiclebody is shown at 1 and the door leaf at 2, this being represented asslightly open.

The door leaf 2 has at the side a cut-out portion 3 cooperating with therabbet of the frame 1. On the respective opposite faces of the saidcut-out portion and the rabbet are disposed rubber bands land 5. Thesaid rubber bands are corrugated at 6, as shown in Figure 2. The saidbands are engaged when in the closing position by their corrugations orteeth 6. I may dispose along the height of the said cut-out portion andthe rabbet one or more sets of rubber bands. The corrugations or teethmay have any suitable shape, and the bands may consist of other materialthan rubber, provided such material has a certain elasticity. Thecorrugations may be replaced by projections of suitable shapecooperating with corresponding recesses. I may employ only one elasticfacing,

a the other facing member being rigid.

It will be readily understood that all disagreeable noise from vehicledoors will-be prevented by the use of the aforesaid elastic 'acings,since the cut-out part of the door leaf will rest upon the rabbet of thedoor frame through the medium of the rubber facings.

All slight motion of the door leaf Will be absorbed by the elasticaction of the rubber bands which are in mutual engagement by theircorrugations or teeth.

The said facing device can also be employed to advantage for otherpurposes, and chiefly for vehicle bodies and for building construction,upon all occasions in which it is desired to prevent noise between twoparts in contact which are adapted for relative motion.

Claims:

1. The combination, with a door, and a jamb having a surface adapted tolimit the movement of said door, of rubber strips secured to saidsurface and to the contacting surface of the door, each of said stripsbeing transversely corrugated to form hills and valleys, whereby, whenthe door is closed, each of the hills on the one strip will enter andcontact the portion of the other strip which forms a valleysubstantially as and for the purpose set forth.

2. The combination with a door and a jamb having a surface adapted tolimit the.movement of said door, ofresilient strips secured to saidsurface, and similar strips carried by the contacting surface of saiddoor, each of said strips being transversely corrugated to form hillsand valleys, and so positioned that, when the door is closed, each ofthe hills on one strip will contact upon a portion of the other stripwhich forms a valley, substantially as and for the purpose set forth.

3. A door holder and shock and vibration,

absorbing means primarily for hinged automobile doors mounted to swingagainst the door frame or jamb member, consisting of a pair of mutuallycooperative engagement strips, one strip to besecured along the ed e ofthe door remotefrom the hinges and t e other to be secured along thedoor jamb, said strips each having transverse corrugations to form hillsand valleys and so positioned respectively on the door and jamb thatwhen the door is closed the hills on one strip will enter the valleys ofthe other strip whereby the strips will preveht a. vertical movement of.

the door with respect to the jamb and the strip on the jamb will alsotend to support the door.

In testimony whereof he has signed this specification.
